1.1 Characteristics of organisms

Organism 으로 분류되기 위한 특징 7가지

1. Movement
2. Respiration
3. Sensitivity
4. Growth
5. Reproduction
6. Excretion
7. Nutrient

Movement §

위치가 이동하는 특징

식물도 동물 만큼은 아니지만 움직인다.

Respiration §

Glucose를 이용하여 에너지를 만드는 화학 반응

O₂의 사용여부에 따라 2가지로 나뉜다.

Aerobic respiration §

O₂를 사용하는 respiration

Equation $C_6{H}_{12}{O}_6+6O_2\to 6C{O}_2+6H_{2}O+\text{Energy}$

Anaerobic respiration §

O₂를 사용하지 않는 respiration

Equation $C_6{H}_{12}{O}_6\to 2C_2{H}_{5}OH+2C{O}_2+\text{Energy}$

---

Sensitivity §

react to environment change

---

Growth §

getting bigger

---

Reproduction §

make new organism

---

Excretion §

emit unwanted substance (from respiration / digestion)

---

Nutrient §

get a substance to get energy for growth, metabolism
